UNITED STATES CHARLES M. sU'r'rLE,

WEA'rnEn Application iled December This invention relates toimprovements in weatherstiipping, having for an object t provide a noveland highly eiiicient form of weatherstripping for sliding window sashes,

F whereby the same will be proofed against. the passage of coldair,.water, snow, soot and other undesirable matter thereby 'andadditionally, will-,be alfor'ded means which will effectually serve toinsure free and unbinding siiding movement'of an', equippedv sash,irrespective of shrinkage or swelling of the saine under'influence ofdifferent atinospherical conditions, the weatlierstrip constructionbeing such that it will provide aconstant bearing pressure or tensionand contact upon and with the sash and by consequence, will at all timesserve to cushion the' same hence maintaining the sash constantly inproper position forslidiiig ni'ovenient in its frame and holding itagainst oblicctionable relative movement with varying atmosi'ihericalconditions, aswell as avoidH ing rattling or vibration thereof.

It is an equally important object of the invention to provide aweatherstrippingof the character mentioned which may be advantageouslyused upon the sides, tops and bottoms of a sliding window sash,affording a sashv so equipped with means for positively proofing thesame against the passage of air or iiiatterbetweeii it and the casing orframe therefor.

VYet another object of the invention may' be stated to provide .aweatherstripping which will serve as an edectual guide for an equippedsash during. sliding of thersame and which, is yformed with a resilientcon*`Y tacting portion whereby a: cushion-like contact between it andthe adjacent marginalr portions of a window ly maintained.

Other objectsofthe inventionfwill `be in part obvious and in partpointed out liereinafter.

In order that the invention and its mode of operationinay bereadilyunderstood by persons skilled in the art, I have inthe sash willbe constantaccompanying illustrative drawings,l and -in l the detailedfollowing description based thereon, set out one possible embodiment ofvthe saine. j y

STRIPPING.

Figure 4 is a similarv view wherein the weatherstripping has been shownas being depressed by the application of pressure thereto from anengaged portion of av sliding window sash, the sash being fragmentallyshown in dotted lines herein, and

Figure 5 Ais an end elevation of a slightly modified form of theweatherstripping.

Havingmore particular reference to the drawings, in connection withwhich likev characters of reference indicate correspond-l ing partsthroughout, the improved weatherstripping may be stated to comprise abody portion formed of resilient or yieldable nia-1" terial, 4thematerial shown herein being sheet metal wherein such material is formedwith oppositely disposed basal lflanges or portionsV l and 2,constituting the body portion proper of the improved weatherstripping,while a longitudinally disposed angularly extending guide rib 3 isformed in this bodyportion of the vweatlierstripping by bending a partthereof upon itself in a manner as is clearly 3 is an end elevation ofthe im-4 illustratedin the Figure 3. In order that 'the 'basalportionvorflange 1 of the body of the weatherstripping may be providedwith means, resilient or yieldable iii'nature, which will maintaina-constant pressure or tensioning contact with an adjacent marginalportion of'a'slidiiig window sash, said portion is formed withanupstruck or vbent transversely curved portion 4 longitudinallythroughout itsV entirelength, it being noted that the said transverselycurved portion 4 is formed intermediately of the opposite sides of thebasal flange l and by consequence, that those portions` of the flangebordering said curved vportion will `forni a supporting or contactingmediuiii-with the adjacent surface or portion of a4 window` frame Freceiving the stripping, while the transversely curved portion 4t will.be iiiaintained away from saidsurface of the frame F land byconsequence,"will'provide the,

weatherstripping with acushioiiinglilre engaging or-contacting'ineansadapted 'to contact or engagewithv an adjacent marginal yportion of anequipped window sash S. -In

ica

this fashion, i1; yWill be appreciated' that the CTI utility., orefiiciencyv of, the transversely curved spring or cushioning portion iwill in no way be affected by the presence ofthe angularly disposedlongitudinally extending guide rib 3.

The basal portion or flange 2 upon. theopposite side of the guide rib 3is disposed at an obtuse angle with respectto the adjacent-V side ofsaid rib 3 as is shown in the Figure 3, the outer side or marginalportion ofthe basal flange@ being arranged in a plane corresponding tothat in which the outer portion ofthe flange l is afranged,4v hence,af-` fording the completed with a supporting surface which will insureproper positioning` of the longitudinally disposed guide rib-Swithrespect to the receivinggroove -g therefor formed in the adjacent inrginal portion of the equipped sliding window sash S. Y 1

In equipping or installing` the improved weather stripping in or upon awindow equipped with a sliding sash suchI as is shown herein, a drivenheaded, screw-threaded v or similar fastening deviceor devices is orareY passed through the outer portion of the basal flange l as isindicated by the numeral 5, such fasteners being engaged in ad` jacentportions ofthe window `frame F and hence, properly locating theweatherstripping with respect to the coacting marginal portion oftheequipped window` sash S and further, preventing relative movement asbetween such weatherstripping and the frame F or the sash S. It willbethus seen that while this particularly anchored portion of therbody ofthe weatherstripping will be held against movement, the opposite sideor` basal portion 2 thereof will bepermitted of a comparatively limitedsliding movement with respect to the supporting` orreceiving surface ofthe window frame F, asis indicated in ythe Figures land 2. Inthose-instancesfwhere the. weatherstripping is attached to the oppositeside ofthewindow sash S, certain of vthe window frame guidestrips e arerabbeted asis indicated by the numeral G hence Jermittinn' a free orslid-v ing portion of `the basal flange 2 to vbe movably engaged thereinas is clearly shown in the Figure l. In this particular adaption orusage of the weatherstripping, the opposite sidesor marginal portions`of the equipped window sash S are formed with the Vg-rooif'es glongitudinally throughout their respective lengths and into thesegrooves g, the longitudinally disposed guide ribs 3 oftheweatherstripping are slidably introduced; the formation of the guideribsY 3`being such as to insureV a slight frictional Contact as betweenthe side walls of the engagedV grooves y g, whereby to prevent relativemovement of this particular point, whilethe outwardly curved portionstof the basal flange l con; tact with an adjacent portionl of thecorreweatherstripping l sponding marginY or side of the window sash S asis clearl, [shown in thesaid Figure l; the opposite asal portion orflange 2 contacting. witha part. of the corresponding guide of thewindow sash S, while the free outersideor margin thereof has sliding ormovable. engagement with the adjacent portion of the window-y frame Freceiving such guide. By reason of this contact as between thetransversely or outwardly curvedportion l ofthe basal. flange -1 with-the'adja'cent marginal portion ofthe window sash S, it Y will beunderstoodthat a` constantpressure or tension and contact will behaduponand" with/the adjacent portion of the windowv saslr S, therebypositively proofing 1 they same against the admission oflair or matterby it,- that is, betweenv it and theframe Fyreceiving the same.Likewise, this constantly applied pressure, tension and'contact willserve as means for eifectually bringing about the proper positioningvof' the slidable windowl sash S in the frame F whereby-saidsash'lwill'- be at all timeszpermittedlof free and un binding slidingmovement. Likewise, because of this peculiar mode ofengagementj4 asbetween `the weatherstripping and the. slidable sash S, itl will beivappreciatedA `that v the weatherstripping will compensate forr shrinkageor swelling of the v sash Sv or its. frame F by reason of the subjectionof the same to `different or varying atmospherical conditions..Consequently upon this, the-window sash S'will4 not only beconstantlymaintained in-position for free and unbinding sliding movementin the frame FQ but like wise, said sashwill-beheld-positively againstrelative movement with'respe'ct to said framek and against objectionablevibration or rat, tling. rThe guide 3 sliding; within the groove n g ofthe window sash S will serve not only as a weathersealing or proofingmeans for the equipped sash, but likewise, wil'lrserve to insure asabove inferred, themaintenance of said sash in proper os-itiony with theweatherstripping and witr the frame Fatl all times. Y

With adaption or arrangement lof theimproved weatherstripping f to thebot-toni or., top marginal portions of a sliding sash'S-'g theweatherstripping is similarly anchored or secured to thereceivingframeFftherefonl in positions to be engagedby the upper or lowermarginal portions of thesashSfwhen suchsash is slid into engagementtherewith: Upon contact of an equipped sashS-withfthe weatherstrippinginthis particular adaption@ thereof, the transversely Ycurved portion 4-ofthe basal flange l willfbef-exed upon itself-fl and by reason of thetension so applied: there-- to, a positive weatherprooiingcontact willYbe established as between itand the adjacent-or responding to thegrooves g aforesaid, and into this'groove g, the angularly disposed,longitudinally extending guide rib 3 is slid ably engaged, thus offeringa further proofing or sealing means for the resultant connection orjointure.

In the Figure 5, I have shown a slightlyv modified form of the improvedweatherstripping. Herein', the weatherstripping is constructed ofmaterial corresponding to that from which the weatherstripping shown inthe preceding embodiment is formed; the device including basal portionsor fianges l and 2 while an angularly disposed longitudinally extendingguide rib 3 is formed between the flange portions l and 2. The basalflange l is provided with a longitudinally disposed transversely curvedportion 4 arranged intermediately of the opposite side of said basalflange, while the basal flange 2 is formed with a transversely curvedlongitudinally vextending portion 7 throughout its entirelength, thus,affording said basal flange 2 with a spring or resilient or cushioningcontact means engageable with an adjacent marginal portion of anequipped sash S and insuring the maintenance of a completeweatherprooiing contact or engagement as between the same and saidequipped sash S as well as maintaining a constant pressure or ltensionthereupon. This formation of the transversely curved longitudinallyextending portion 7, will, as will be understood, accentuate theapplication of the position retaining pressure exerted by thetransversely curved longitudinally extending portion si upon itsparticularly adjacent portion of the equipped sash S, and byconsequence, it will beappreciated that said sash will vbe positivelyretained, at all times, in proper position with respect to the frame Freceiving At this point, it should be also noted that shoulders 8 and 9are formed adjacenty the basal portions of the opposite sides of thelongitudinally disposed guide rib 3', between the same and itsconnection or jointure with the transversely curved longitudinally,extending portions 4: and 7. These shoulders, which are ,arranged atsomewhat obtuse angles with respect to the adjacent or opposite sides ofthe guide rib 3 will serve as means for further accentuating` the springor cushion like engagement of the weatherstripping with the adjacentmarginal portion of an equipped or receiving sash S,

and furthermore, will permit of free or uninterrupted spring contact asbetween the opposite sides of the basal portion of the guide rib 3 andthe adjacent side wall of the groove g receiving it. v

Manifestly, the construction shown is capable of considerablemodification and such modification as is within the scope of my claims,I consider within t-he spirit of my invention.

I claim:

l. A weatherstripping formed from a single strip of spring metalincluding space-d basal portions and an intermediate portion formed intoan upstanding longitudinally disposed guide rib throughout the length ofthe strip, one of. the basal portions having its intermediate portionbent outwardly through its length and curved transversely, the otherside of said basal portion beyond the transversely curved part beingflat and normally arranged at an angle to the adjacent surface of areceiving frame and adapted to be freely slidable over the same, andthat side of said basal portion in proX- imity to the rib being inclinedat an obtuse angle to the transversely curved part and to the adjacentside of the rib and being at times adapted to contact with the adjacentsurface of'a receiving frame to increase the p resiliency of thetransversely curved part, the remaining basal portion on the oppositeside of said guide rib being disposed at anV obtuse angle with respectto the adjacent side of said rib and at an angle to the adjacent surfaceof the lreceiving frame whereby to be freely slidable thereover, thefree edge of said last mentioned basal portion being arranged in a planeapproximately corresponding to that in vwhich the plane portion of therst mentioned basal portion'is arranged. y

I 2. A weatherstripping as claimed in claim l wherein the last mentionedbasal portion is odset adjacent the rib and arranged at an inclinationto the rib, and said inclined por-v tion being symmetrical with'yrespect to the inclined. part of the other basal portion and being attimes adapted to contact with the adjacent surface of a receiving frameto in-l crease the strip.
